Appendix A. REMOTE CONTROL

OPERATION

This appendix describes the remote control operation of the SNM-1002 LinkSync™.

• Firmware

number: FW/6535-3G

• Software

version: 4.1.5

Note: The firmware referenced in this manual may be an earlier version of the actual
firmware supplied with the unit.

A.1 General

Note: Under normal operation, the MIDAS NMS configures and controls the LinkSync

modem for all the functions it provides using the remote control port. For purpose of this
manual, the complete list of Remote Commands are provided. However, for practical usage,
these remote commands will likely never be used nor required by an operator.

Remote controls and status information are transferred via an EIA-232 serial
communications link. Commands and data are transferred on the remote control
communications link as US ASCII-encoded character strings. The remote communications
link is operated in a half-duplex mode. Communications on the remote link are initiated by
a remote controller or terminal. The modem never transmits data on the link unless it is
commanded to do so.
